Performance comparison of PTFE membrane, PVC membrane and ETFE membrane

Characteristics of PTFE membrane materials:

PTFE membrane is a kind of material coated with polytetrafluoroethylene resin on superfine glass fiber fabric. This kind of membrane material has good welding properties, excellent UV resistance, anti-aging and flame retardancy. In addition, its antifouling and self-cleaning performance is the best of all building membrane materials, but the flexibility is poor, the construction is more difficult, and the cost is also amazing. Following there are its characteristics:

 

1. High strength, good durability, fire retardant, good self-cleaning and not affected by ultraviolet light.

 

2. With high light transmittance, and the light passing through the membrane material is natural diffuse light, will not produce shadow, also will not produce glare.

 

3. The reflectivity of solar energy is high, so the amount of heat absorbed is very little

Characteristics of ETFE membrane materials:

ETFE, known in Chinese as the ethylene tetrafluoroethene copolymer, is a scratch resistant, abrasion resistant, heat resistant, corrosion resistant, insulating and safe material. Ultra-light weight: thin and light film. Superior earthquake resistance and convenient construction. Good durability: climate adaptation:-200 ~ 150 °C, more than 15 years of severe weather.

 

 

Features of PVC membrane materials:

Compared with PTFE, the strength and fire resistance of PVC membrane materials have some differences, and the service life of PVC membrane materials is generally 7 to 15 years. In order to solve the problem of self-cleaning of PVC membrane material, PVDF (polyvinylidene fluoride acetate) membrane material is usually coated on the PVC coating.

 

Foreveralseal provides high quality ePTFE membrane. Eptfe membrane actually is unsintered PTFE films and tapes which are produced by a paste extrusion process, called “extruded” PTFE tapes and films too. Unsintered extruded PTFE is used in wire and cable insulation for extreme chemical and thermal environments including aerospace power cable, coaxial cable, thermocouple wires, membranes in batteries, convoluted hose constructions.

 

Our products have these characteristics:
High dielectric strength

Outstanding chemical and thermal resistance

Tight thickness tolerances

Long joint free lengths

High tensile strengths that support fast wrapping speeds.

Two kinds of ePTFE film

 

1. LOW DENSITY ePTFE FILM & TAPE

Low density PTFE film & tape produce micropore through stretch and under a certain specific and tightly controlled conditions to achieve low dielectric constant and high tensile strength for high frequency microwave coaxial cable applications in data transfer,militarty and medical field.

 

2. HIGH DENSITY ePTFE FILM & TAPE

High density PTFE films/tapes provide superior electrical and chemical of the standard serious. It’s recommended for heating cables,aircraft and automotive cable in highly critical military,aerospace and high demand industrial.

 

Foreverseal is a privately owned company with a very stable financial background, who is a professional manufacturer and exporter of high quality PTFE TAPE from Jun 2009. Our PTFE TAPE have obtained UL, CE, WRAS, RoHS...Stable and good quality lead us to keep long and standing business relations with old clients and get more new clients from middle & high quality markets. Now we have a team of qualified engineers and employees, more than 80 workers. We are not the biggest one, but the best partner you need.
